Abstract

The study proposes to provide data for the application of high volumes of waste glass fractions as partial replacement for cement in building materials. Using contaminated waste glass helps to reduce the pressure on landfill and environmental pollution. Most of existing research focused on a cement replacement ratio below 30%, which still has potential to be improved. The organic contamination could cause different influences on hydration and fresh workability. The hydration characteristics of pastes mixing cement with different contents of waste glass fractions were investigated by calorimetry. The products of hydration were observed by XRD and FTIR. The microstructure properties of different waste glass content samples were identified by SEM. The influences of organics and the glass fraction on porosity and pore size distribution were investigated.
